migrate triage-ops to two different K8S clusters

What does this MR do and why?

我们计划将原 triage-ops 部署所在的 K8S 集群进行下线操作，并将 triage-ops 的 staging 和 production 迁移到另外两个 K8S 集群中。同时：

• 由于分别位于不同的集群中，因此 K8S 命名空间可以都改成 triage-ops；
• 原来的域名设计不太合理，两个环境的域名分别改成：
  • production环境：triage-ops-tprd.gitlab.cn => triage-ops.gitlab.cn
  • staging环境：triage-ops-tstg.gitlab.cn => triage-ops-stg.gitlab.cn
• 证书由以前的免费证书改成泛域名证书。
